Was this his way of telling me that we are exclusively dating now or am I wrong?

I was texting with the guy I've been dating for 3 weeks. He brought up the fact that he really wanted to sleep with me when we were hanging out at my house earlier today. I responded that "I'm not interested in sleeping with a guy unless I am in a committed relationship with him". He then responded that he "feels the same way and he is looking for a committed relationship too"...

... Was that his way of telling me that we are in a relationship now? I can't tell for sure based on this response.
